TRS: Ultra-Thin Polymer Concrete Overlays for Bridge Decks

Status: Complete
Report Date: 10/15/2012

Summary:

Ultra-Thin polymer concrete overlays for bridge decks improve the friction and durability of bridge decks while sealing them against the corrosive effects of deicing chemicals. However, there are concerns that these overlays may trap water in the concrete surface, accelerating deterioration due to freeze-thaw cycles. MnDOT needs more information on the effectiveness of thin overlays in extending the life of bridge structures, the effectiveness of overlays in reducing accidents by increasing friction, and the performance of overlays over time.
